PULSUS DICROTUS Meaning and
Definition
-
Pulsus dicrotus is a medical term used to describe an abnormal pulse waveform characterized by bifurcation and double systolic peaks. The term is derived from the Latin words "pulsus" meaning pulse, and "dicrotus" referring to double beating. The pulsus dicrotus is often observed in individuals with certain cardiovascular conditions or pathologies, and it can provide valuable diagnostic information about the functioning of the heart.
The pulsus dicrotus is typically identified by a palpable double systolic peak felt during the examination of the radial pulse. The first peak corresponds to the ejection of blood during systole, while the second peak occurs immediately after and reflects the reflected wave from the periphery. This results in a waveform that appears to have two beats for each cardiac cycle.
Several cardiac disorders can give rise to a pulsus dicrotus, including conditions that affect the aortic valve or aorta itself. For example, aortic regurgitation, a condition in which the aortic valve does not close tightly, can cause a pulsus dicrotus. Additionally, certain forms of hypertrophic cardiomyopathy, a disease affecting the heart muscle, may also exhibit this abnormal pulse waveform.
The presence of pulsus dicrotus can aid clinicians in making a differential diagnosis and identifying the underlying cardiovascular pathology. It is a valuable clinical finding that should prompt further investigation and may guide further treatment decisions.

Etymology of PULSUS DICROTUS
The term "pulsus dicrotus" has Latin roots.
The word "pulsus" comes from the Latin verb "pulsare", meaning "to beat" or "to pulse". In the medical context, it refers to the rhythm or beat of the pulse.
The word "dicrotus" has Greek origins. It is derived from the Greek noun "dikroton", which means "double-beat". This term describes a pulse that exhibits a double wave or a secondary beat.
Therefore, "pulsus dicrotus" translates to "pulse with a double beat" or "double-beating pulse" in English.
